Indmar Knock Sensor 06+ Post & Socket Only

Improved replacement socket & stud for 2006 and newer Indmar engine knock sensors. Newer version socket is two pieces where the socket stays mounted inside the engine block and post comes out with sensor.

Product Specs:

• Indmar Part# 495039B-1
• Stud & Socket Only, Actual Sensor Sold Separate - Use Part # 551392
• Not Used on LCR, LTR other Indmar low-cost motors
• This Socket and post replaced the one-piece post & nut.
• Socket is threaded all the way through, allowing water to drain from the block once the post is removed. (It is still recommended to remove the socket to make sure all the water drains out.)
• ***NOTE*** Make sure to never install anything in between the block and the knock sensor other than what is stock. It is crucial for the engine's ignition system that the knock sensor has a proper connection to the engine block.
• Sold individually (Qty 1 = 1 Post & 1 Socket)
